I had limwire for yeeeaaars, and never had a single problem, every single person I know that had limewire got a virus, it finally happened to me maybe a month ago and it sucked major ass, got rid of it and didnt learn my lesson and downloaded version 5, its ok, its format is different and I think harder to use, and its harder to narrow a search down. But I didnt like it enough to stop using it before something else happened.
